The thermal response of gold and platinum spherical nanoparticles (NPs) upon cooling is studied through atomistic molecular dynamics simulations. The goal is to identify the morphological transformations occurring in the nanomaterials as well as to quantify their dependence on temperature, chemistry, and NP size. For diameters smaller than 3 nm, the transition temperature from a melted/amorphous to a highly crystalline state varies considerably with NP size.

The European Commission advocates the integration of Safe and Sustainable by Design (SSbD) principles early in the innovation process to streamline market introduction and mitigate costs. Within this framework, encompassing ecological, social, and economic factors is paramount.

- Experimental aerosol exposure (AE) systems at the air-liquid interface (ALI) provide a more realistic way to assess inhaled contaminant toxicity compared to traditional submerged methods but need thorough characterization.
- The study assessed a CULTEX® exposure chamber's performance by examining how different system parameters influenced the deposition efficiency of CeO nanoparticles and their effects on alveolar cells (A549) and small airway epithelial cells (SAECs).
- Results showed that even brief exposures to filtered air can significantly affect cell health and gene expression, highlighting the importance of customizing system settings for reliable outcomes in toxicity studies.
The agricultural sector plays a pivotal role in driving the economy of many developing countries. Any dent in this economical structure may have a severe impact on a country's population. With rising climate change and increasing pollution, the agricultural sector is experiencing significant damage.
